House of the Dead is the type of series that should never, under any circumstances, be taken seriously. Every game in the series plays out like a particularly bad B-horror movie, but that's the point. When Overkill came along, no one was expecting much—just more of the same. What we got took everything to another level of camp, and it was a glorious ride. If you have some friends and an itch to mow down zombies with characters that curse like sailors, this won't disappoint.

Siren: Blood Curse (2008)

The original Siren remains as one of the most terrifying games I've ever played. There's something about seeing through the eyes of the person, or thing, that wants to kill you as it creeps up behind you that just isn't right. In Blood Curse, we got more of what made the first game great, only this time with more polish, better visuals, and extra content. I dare you to try to sleep without the lights on after playing this game.

Plants vs. Zombies didn't just introduce us to some of the most adorable zombies ever; it was also a highly addictive game that turned the tower defense genre on its head. It was cute, quirky, and often hilarious, and while it might not have taught us anything that could help us survive the zombie apocalypse, it certainly gave us something to play until it happens.
